Total number of Turbogenerators (120,000 MWA)

Total number of Hydrogenerators (26,600 MWA)

The Ansaldo Energia generator product is continuously upgraded and enhanced by a dedicated R&D organization, exploiting extensive operating experience.

The increased power boundary for the specific type of coo-ling, more flexible operating capabilities and excellent reliabi-lity are the result of Ansaldo Energia R&D efforts. Ansaldo Energia portfolio is based on turbogenerators which are standardized in terms of power output range, type of coupled turbine and installation. The “make-to-stock” production system for the main gene-rator body results in reduced time to delivery for both com-plete units and spare parts. Ansaldo Energia turbogenerators combine proven design, manufacturing and commissioning skills with the Company’s well known flexibility in matching Clients needs with tailo-red solutions and customizations. Moreover, CAD/CAM technology is applied extensively in the design and manu-facturing process to improve flexibility in satisfying Clients requirements and to reduce workshop manufacturing time.

Ansaldo Energia began working in the field of Power Gene-ration with the installation of the first hydroelectric plants at the start of the last century. Since the early 1920s, Ansaldo Energia has focused on turbogenerators when the company began air cooled turbine generator production. Since 1950 more than 1000 air cooled generators (both round and sa-lient pole rotors) have left the company’s Genoa production facility for installation worldwide, among them over 500 units were air cooled turbogenerators in the 10-330 MVA range. Ansaldo Energia has also gained extensive experience in the design and construction of hydrogen and hydrogen-water cooled turbogenerators since the 1950s, manufacturing more than 200 units in the 40-1220 MVA range. The total installed capacity of the turbogenerators manufac-tured by Ansaldo Energia amounts to over 100,000 MVA. Ansaldo Energia turbogenerators can be installed in various types of application including:

• combinedcyclepowerplants• steampowerplants• geothermalpowerplants• nuclearpowerplants• Synchronouscondensers• Specialtestfacilities(pulsegenerators)

A Proven design

All generators are designed by Ansaldo Energia, exploiting the experience gained working on these proven standard components. Generators are designed in compliance with IEC 60034-1, IEC 60034-3, IEEE C50.13 and IEEE C50.12.The design takes account of requirements for both conti-nuous and flexible operation, such as daily start up, in a re-liable way.

The design of generators assures safer operation also in the worst conditions: • faultsupport,e.g.suddenshortcircuitswithoutdamage• compliancewithregionalseismicregulations

Ansaldo Energia turbogenerators can be coupled to steam and/or gas turbines with or without gearing.

Product oriented R&D guarantees constant, gradual evolu-tion for both sub-components and unit performance, in line with Client needs.

For example, in the last decade the Resin Rich class F 4675 insulation system has been upgraded to deliver higher ther-mal conductivity.

High Quality Manufacturing

Raw materials are purchased from qualified suppliers and machined in Ansaldo Energia. Both main component ma-nufacturing and final turbogenerator assembly are carried out in Genoa factory, where modern manufacturing facilities permit high technology operation plans. Checks during the different assembly steps are registered and certified in the framework of an efficient Quality Mana-ging System.

A rigorous Test Program

All Ansaldo Energia turbogenerators are subjected to a stan-dard program of tests, including:• statorcoreloopmagnetization•windingresistance• insulationresistance• staticanddynamicimpedancemeasurement• withstandovervoltagea.c.test• rotormechanicalbalanceandrotoroverspeed

Running tests and special tests (e.g. bump test, partial di-scharge) can be performed on the assembled generator, if requested. All tests are performed in compliance with IEC and IEEE standards.

Flexible arrangement for Transportation

The overall dimensions of turbogenerators comply with rail transport limits. Turbogenerators for gas turbines can be transported in as-sembled form, reducing shipping costs and simplifying on-site erection and alignment work. In special cases genera-tors can be shipped only partially assembled for completion on site. Fully tailored hydrogenerator design allow to opti-mize both transportation to site and compliace to Client’s requests.

recognised high skills and excellence in commissioning and after sales services

Ansaldo Energia offers a full range of services and quali-fied personnel for erection and/or supervision, startup and testing. The availability of standard arrangements, and in some cases packaged solutions, ensures rapid, problem-free erection and startup.Ansaldo Energia Service Organization provides worldwide technical assistance in the fields of maintenance, spare part supply and preventive maintenance programs, ensuring that customers are in the best position to achieve optimum ope-ration. Ansaldo Energia Service Organization also provides Clients with in-house personnel training, supported by dedicated didactic materials. Our comprehensive and reliable after-sales services are re-gularly reviewed to assimilate operating experience. Diagnostic tools are available to monitor generator parame-ters and behavior continuously, in order to detect ageing trends and address maintenance activities.

These advanced diagnostic and monitoring tools include (non exhaustive list):

• Detectionofanomalousconditionofthecarbonbrushes (sparkling activities and wear threshold) in the slip rings housing;• PartialDischargeforstatorwinding• Fluxprobeforrotorwinding• Shaftvoltagesandcurrents• Statorend-windingvibration

These systems are available for online or local monitoring.

Ansaldo Energia power plants are connected directly to the Ansaldo Energia Diagnostic Room, offering 24/7 remote dia-gnosis.

Moreover, thanks to Reverse Engineering capabilities, An-saldo Energia can offer complete maintenance, restoration and modification of non-proprietary, third party generators.
